' In the center Vof casing 21 an opening 34 is extended through the rib 24 to the passage connectingV the twochambers 22 and 23, and in this opening a tube 35 is connectedk which yin turn' isfconnected to the pressure chamber ,way of a passage 36 .bored'in'ithe Vcasing 1 seat'2f6.'v On the opposite side of'opening 34 `an opening 39 Vis extended through'casing 21- Vinto chamber 22,. lBetween this opening'and themid-section of the vertically disposed.

seated on Vthe seats 29 `and 26, as shown in full-line in Fig. V5, chamber 18 is connected by way of'tubes` 35 and 41 with the outletV chamberv 4.V Under such conditions, if'the pressure in I chamber 18 will he atmospheric YKerfpr'essureor lower, as will presently appear,

f ber 8; VDue to this lunbalanced pressure conand hence vlow-er thanthe" pressure in chamditionj on diaphragm 14 the diaphragm is flexed upwardly and valvev 11 lifted from its seat, thereby permitting thec'ondensate in the trap Vto'beforced out through pipe 8. Howlv s' ever, when valves 27 andr28'f'are vmoved to the v positions shown-by the dotted lines inlig.` v 5, Yt'hat'is, when they yare seated on the seats l25and 31, vchamber V18 is connected to c ham-k ber 3 by way of .tubes 35and 38. With such:

Toiinsure the .valve 11 being heldopen until the `condensate is suliciently discharged yfrom chamber oncethe discharge Yvalve is -operated,-a sleeve-like Venturi tube42 is littedfinj the vertical tubular part of the outlet ,66j chamber 3.l For assembling this sleeve a plug 43is threadablyp'rovided in the'top of tube- Y formingwally 2, and the ltop of Sleeve 42 is threadfedtojscrew into threadsl out in the upper end vof wall 2'ata pointslightly below "orifice" 8. lower Vend' of the sleeve 'inturn is tapered to fit tightly l into avtaper-receivingV opening v44 provided at the point where theYA vertical part of wall 2 meetsfthe horizontal portion thereof.

In the centerv of sleevek .42, which isre-f stricted, a hole 45 is drilledV and hence dueto Y a'well known action when lthe water is forced through-.this tubev with 'theA opening'l of valve 11 a suction-'is set up in chamber 46 which surrounds the middleportion of thetube. This j y Y suctionin turn is communicated to chamber 575;" W

18 by tubes 41 and 35,'thus providing a pres- Y sure in chamber 18- which is lower than the Y.

pressure in chamber 3 irrespective of whether ,y

the normal `pressure in thatA chamber'is def lgO l I creasedby the opening in valve l1 or not.

For automaticallyoperating valves 27 and p 28 afloat 47 anda weight48 are employed.

The assembly o-fthese is illustreitedmostY f clearly in Figs; 3 and 4 and' asfshown com* prisesa rod 49 to which the float is attached andan arm 51 on which the'weig'ht isv sea?Y cured. The end of rod A49 opposite the float is secured to a ring 52 while the end'of arm 511 Y l `opposite the weight .has aholei5'3provided init, andl through this h'oleand'theiring 52 Y a pin 54.is`rv mounted to functionas` a pivot? therefor, the-pin'itself -fbeing supported in a v n pair of brackets 55` disposed on thezioorof casing 1. For f holdingv the` `pin "in "these" brackets a cotter` pin 56- is employed.y

s Adjacentarm 51 which ismounted next toA ring 52 on pin-54 'a collar 57 is located'.` This collar isfequipped-with apin 58'which'is posed in line with and attached to the endof; the valve stem'BQ'; Hence any rotationlof.the`

collar is adaptedto move valves 27 and'28ff Y Forreasons of assembly pin 5.4is 'provided with portionsof two differentdiameters.; f

@ne of these is' the same as thefopeningslin* arm 51V and ring 52,V andthe other, .which is smaller, is the same as that ofthe opening in the collar 'awasher 61-is mounted'.`

To rotate co'llar'57 and mve" stemBOa'pairy of lugs 62 and 63 arejprovidedatfdiametrically opposed'positions on ring 52and 'arranged to project over 'the' outer edge' of the' lower end of arm` 512which is semi-'circularV inv shape and adapted to'engag'e shoulders 64l and`65 formed on arm 51. kThese shouldersare disposedy at an angular distance'fromjeachother which isc` less than 180 fora purposewhich willavpres-V ently be apparent. y f

lug 66 is formed on the side 'of arm "51`ad-fjacent the collar and at'a'point thereontoiengagefoneor the otherKV end of a double "ended-v latch 67 pivotally5`mo'unted Vontheinner end-f cenar 57. About the edgejef thefcouar 57 a; flange 59 Ais provide-dwhich is'adapted ,to lit' over the larger part 'ofcpinf 54 and v'adj acentA` lit Y y Y 12h` Y Tocomplete' the connection V'tojc'ollar E57 aQ of'pin- 58.l ',To permit themountinglofthis f latch the yflange l59is cutaway overy a sector of `its circumference. Withsuch an arrange;

ment, with the float 47 arranged toride on the surface ofthe condensateV deposit-infchainbei' 2 engagesA the shoulder 64A on-arm 51 and-2 thereby causes the weight 48 to be rotated about the pin 54. As soon asthe center of gravity of the weight ismoved over'the een-` ter` of pin 54 the weight falls-due 'to-gravity and iii falling lug 66j on arm 51 engages the shoulder 68 of latch 67. By reason ofthis and the latch-being connected to the col-lar57 y the'latte'r is rotated by the weight in a backward direction, as shown inthe drawings, until the valves 27 krand 28 are seated :on the` seats 26 and 29, respectively. As previously described, whenv these valves are in such position chamber 18 is connected totube41and valve 11 is opened. Conversely, as the level-- of the waterisl lowered due to valve 11 being open, float V47 is lowered and in loweringlthej lug 63 on the ring 52 engagesthe shoulder 65 ori-arm 51. v This causes the weight-48 tobe rotated in a direction opposite to that previ! ously referred to. As soon Vas it passes over the center of the pin it again falls 'due to gravity but in a direction such that lug 66 engagesA the end 69V of latch67 whereby collar 57 is rotated to movevalves 27 and 28 against seats 25 p and 31. To insure the proper operationof the valves 27 and 28 pin54" is mounted soit` 50'- willnot rotate and latch 67 isprovided with depending lugs 68a and 69a which engage in notches 686 and 69?) in pin 54; Through the use of these' rod 30' isprevented from moving andthe depending lugs 68a and 69a are disengaged from their respective grooves due to teetering of the latch by engagement therewith of the lug 66'.r With these valves in this position, as set forth? above, chamber 18 is connected with chamber 3. Due to the pressures' on the two sides' of diaphragm 14 being thus neutralized, valvev llis closed by' gravity.

Obviously from the foregoing `the pilot valve mechanfism'is adapted to positively insure the opening and closing of the discharge valve 11 when thejwater` in chamber 3 isat` preselected levels', and the operation of the discharge valve is effected by` 'the pressure available in the trap, or the system to which it is connected. v ,y

While the structure described above is sufficient for use in positive-pressure systems, itis also possible to make use of it in a vacuum system with a few additional features. For use in` such systems a second opening 71 eX- tending into chamber 22 is provided incasing 21 of the pilot valve and a tube 72 extended from this opening through the wall of Casing 1. This tube in turn is connected by van extension 7 3 to the vacuum line ofthe system at `a point ahead of the vc'imdensate level. The purposeof this connection is to provide a vacuum in chamber 3 and also to provide a reduced vacuuminV chamber 18 when it is desired toopen valve 11.* A second opening 74 is also extended through cas-ing 21into chamber 23a-and this connected by a1 tube "7 5 through casing` 1' to .the fatmosphereyor to-a suitable source .of air or steam pressure.

This latter4 connection is made toprovideaJ pressure in chamber 18 which will-.preventthe4 .suction in chamber.Blfpullingthe valve 11` open whenV it is desiredto maintain .that valve closed, and foi-forcing thecondensate out of the trap -whenfvalvelll is open. r :With these provisionswheii'fvalves 27 and1128 are seated on; seats and 31 valve` llffis heldclosed by the atmospheric or Vpositivetpres- .p sure, depending. upon ,theco'nnection in tube;V 75, which is communicated to` Achamber 1-8b`yl Way of'tubes 75 and 35,.Y and when these'fvalvesy areseated on seats'29 and26 `valve 11 isfforced open by reason of chamber 18 being connect-.-

ed by way of tubes andf72withgthe vacuum of the system ahead of the 'condensateglevel and atmospheric `or positive pressurel being communicated to chamber 3 by way of tube 7.5 l and the opening inplug V38 aboutthelvalve stem 30. y' Y y y To prevent dissipation ofthel vacuum in the system .when such` latter connection, is

madea check-valve 7 6y is provided inthe end of tube 38 and a check valve 77 is provided in: the inlet pipe-7. Thislatter checlcvalvev is adapted, however, to `not prevent the lflow' of condensate by gravity into the inlet chamber when' valve 11 is' closed. Under such condi-l tions, as set forth above, avacuum is also established in chamber 3 by the* connection 72, `hence vpermitting thevalve 77'to operateA freely. l y

municated to tube a plug 7 8 is provided in the wall of casing 1 in communication with chamberj4vat a position toipermit the Vcon-.-l

- opposite theend of tube 41, and to provide for connecting the tube 72 withinletchamber when valve 27 is seatedfon seat 25 atube 81 is connected to an Vopening 82 in the plug 32 Vand extended upwardly'in chamber 3'to a .point `above the high water level. Obviously the trap so adapted for use in a vacuum sysioo F ordiscliarging the condensatefrom the trapf when atmospheric pressure only isfcom-` tem will operate under the controlbf the float 47 and the weight 48 in the same fashion as previously described with its use ina pressure system, and as'will'bereadily,appreciatedwhen such connectlonsare provided and' the trap is used in a pressure system? instead of avacuumjsystem the tubes7 2 and 7 5will be closed either by means of lugs or valves suchv as the valves 83 and .84,asA shown in Fg.2. fr 2a Y.

i Among the advantages of the invention'is level in the trap is at preselected levels.V This latter'is/"broug'ht about by the proper spacing of the lugsonth'e ends ofthe'latch 67 and theV spacing between the Vshoulders 64 andf' and Y 'Y the lugs 622 and 63 onV the ring 52 on vwhich the,Vr
